根据国外资料介绍,我们稍加改进,设计了一种自动返回顶料器(图1)。自1976年使用以来,到现在已有八年时间,没出任何毛病,效果良好。顶料器安装在300吨摩擦压力机工作台下面的横臂1上,借两根拉杆2与滑块3相连接。横臂上安装两个往复滑动的滑板4,借弹簧5使两个滑板对紧。滑块上升时,两个滑板支承着顶杆6向上,顶出零件,顶杆是装在压力机工作台的导套7中;滑块继续上升时,呈楔状的导套下端推开两个滑板,滑板就松开顶料器的顶杆,使顶杆恢复到悬吊位置。此时,把下一个零件毛坯放入凹模,继续工作。此种顶料器具有下述优点: 1.提高了工作效率。原冷镦195气门挺柱时,班产为3,000件左右;采用自动返根据国外资料介绍,我们稍加改进,设计了一种自动返回顶料器(图1)。
According to foreign information, we slightly improved, designed to automatically return to the ejector (Figure 1). It has been eight years since it was put into use in 1976, with no problems and good results. The ejector is installed on the transverse arm 1 below the 300-ton friction press table, and is connected with the slider 3 by two tie rods 2. Cross arm mounted reciprocating sliding slide 4, by the spring 5 so that the two skids tight. When the slider rises, the two sliding plates support the push rod 6 upwards to eject the parts. The push rod is installed in the guide sleeve 7 of the press workbench. When the slider continues to rise, the lower end of the guide sleeve with the wedge shape pushes two Skateboard, skateboard to unscrew the ejector ejector, the ejector to the suspension position. At this point, the next parts blank into the die, continue to work. This ejector has the following advantages: 1. Improve work efficiency. The original cold heading 195 valve tappet, the class production of about 3,000; using automatic return According to foreign information, we slightly improve the design of an automatic return to the ejector (Figure 1).
